'''Zarafa''' is a Free Software groupware server. The for-pay enterprise version provides Microsoft Exchange server functionality. For non-enterprise users, Zarafa's ability to function as a back-end for [[Z-Push]], allowing full-fledged, locally served [[Android]] synchronization may be its most attractive feature. On the desktop side, the gratis and libre community version Zarafa supports, POP3, IMAP, CalDAV and an HTTP interface out-of-the-box, allowing Mac, Mozilla and Novell [[:Category:Personal information management|PIM]] applications (i.e. Mac Mail, [[Thunderbird]], [[Lightning]] and [[Evolution]]) to easily connect to its information stores. Note that the KDE PIM suite requires GroupDAV, which is not provided by Zarafa. With additional configuration and integration, using LDAP for contact storage and access is also possible.

Zarafa has a flexible, pluggable user system. If you have a fully functional LDAP or Active Directory server, go ahead and use it. OtherwiseThe default MySQL database backend works fine out-of-the-box, the but a Unix backend is recommendedalso available. If you don't know what to choose, just don't change anything to use the database backend. To configure it If you want to use the Unix backend, edit <code>/etc/zarafa/unix.cfg</code> and change the domain to your own.

Lastly, you'll need to add a user. How you do this depends on the user backend you chose. If you went with the default database backend, an administration tool is provided. Read the man page or run <code>zarafa-admin --help</code> for the full documentation. A quick example is below.
